Rails 6.0.3 (May 06, 2020)

  • Cache compiled view templates when running tests by default

    When generating a new app without --skip-spring, caching classes is disabled in environments/test.rb. This implicitly disables caching view templates too. This change will enable view template caching by adding this to the generated environments/test.rb:

    config.action_view.cache_template_loading = true

    Jorge Manrubia

  • Rails::Application#eager_load! is available again to load application code manually as it was possible in previous versions.

    Please, note this is not integrated with the whole eager loading logic that runs when Rails boots with eager loading enabled, you can think of this method as a vanilla recursive code loader.

    This ability has been restored because there are some use cases for it, such as indexers that need to have all application classes and modules in memory.

    Xavier Noria

  • Generators that inherit from NamedBase respect --force option

    Josh Brody

  • Regression fix: The Rake task zeitwerk:check supports eager loaded namespaces which do not have eager load paths, like the recently added i18n. These namespaces are only required to respond to eager_load!.

    Xavier Noria

Rails 6.0.2.2 (March 19, 2020)

  • No changes.

Rails 6.0.2.1 (December 18, 2019)

  • No changes.

Rails 6.0.2 (December 13, 2019)

  • Fix the collision check for the scaffold generator.

    Ryan Robeson

Rails 6.0.1 (November 5, 2019)

  • The zeitwerk:check Rake task reports files outside the app's root directory, as in engines loaded from gems.

    Xavier Noria

  • Fixed a possible error when using the evented file update checker.

    Yuji Yaginuma

  • The sqlite3 database files created by the parallel testing feature are included in the default .gitignore file for newly-generated apps.

    Yasuo Honda

  • rails new generates a .keep file in tmp/pids. This fixes starting a server via rackup instead of rails server.

    Rafael Mendonça França

Rails 6.0.0 (August 16, 2019)

  • Rails.autoloaders.log! is a logging shortcut to get the activity of the loaders printed to standard output. May be handy for troubleshooting.

    Xavier Noria

Rails 6.0.0.rc2 (July 22, 2019)

  • The new configuration point config.add_autoload_paths_to_load_path allows users to opt-out from adding autoload paths to $LOAD_PATH. This flag is true by default, but it is recommended to be set to false in :zeitwerk mode early, in config/application.rb.

    Zeitwerk uses only absolute paths internally, and applications running in :zeitwerk mode do not need require_dependency, so models, controllers, jobs, etc. do not need to be in $LOAD_PATH. Setting this to false saves Ruby from checking these directories when resolving require calls with relative paths, and saves Bootsnap work and RAM, since it does not need to build an index for them.

    Xavier Noria

Rails 6.0.0.rc1 (April 24, 2019)

  • Applications upgrading to Rails 6 can run the command

    bin/rails zeitwerk:check
    

    to check if the project structure they were using with the classic autoloader is compatible with :zeitwerk mode.

    Matilda Smeds & Xavier Noria

  • Allow loading seeds without ActiveJob.

    Fixes #35782

    Jeremy Weathers

  • null: false is set in the migrations by default for column pointed by belongs_to / references association generated by model generator.

    Also deprecate passing {required} to the model generator.

    Prathamesh Sonpatki

  • New applications get config.cache_classes = false in config/environments/test.rb unless --skip-spring.

    Xavier Noria

  • Autoloading during initialization is deprecated.

    Xavier Noria

  • Only force :async ActiveJob adapter to :inline during seeding.

    BatedUrGonnaDie

  • The connection option of rails dbconsole command is deprecated in favor of database option.

    Yuji Yaginuma

  • Replace chromedriver-helper gem with webdrivers in default Gemfile. chromedriver-helper is deprecated as of March 31, 2019 and won't receive any further updates.

    Guillermo Iguaran‮

  • Applications running in :zeitwerk mode that use bootsnap need to upgrade bootsnap to at least 1.4.2.

    Xavier Noria

  • Add config.disable_sandbox option to Rails console.

    This setting will disable rails console --sandbox mode, preventing developer from accidentally starting a sandbox console, which when left inactive, can cause the database server to run out of memory.

    Prem Sichanugrist

  • Add -e/--environment option to rails initializers.

    Yuji Yaginuma

Rails 6.0.0.beta3 (March 11, 2019)

  • Generate random development secrets

    A random development secret is now generated to tmp/development_secret.txt

    This avoids an issue where development mode servers were vulnerable to remote code execution.

    Fixes CVE-2019-5420

    Eileen M. Uchitelle, Aaron Patterson, John Hawthorn

Rails 6.0.0.beta2 (February 25, 2019)

  • Fix non-symbol access to nested hashes returned from Rails::Application.config_for being broken by allowing non-symbol access with a deprecation notice.

    Ufuk Kayserilioglu

  • Fix deeply nested namespace command printing.

    Gannon McGibbon

Rails 6.0.0.beta1 (January 18, 2019)

  • Remove deprecated after_bundle helper inside plugins templates.

    Rafael Mendonça França

  • Remove deprecated support to old config.ru that use the application class as argument of run.

    Rafael Mendonça França

  • Remove deprecated environment argument from the rails commands.

    Rafael Mendonça França

  • Remove deprecated capify!.

    Rafael Mendonça França

  • Remove deprecated config.secret_token.

    Rafael Mendonça França

  • Seed database with inline ActiveJob job adapter.

    Gannon McGibbon

  • Add rails db:system:change command for changing databases.

    bin/rails db:system:change --to=postgresql
       force  config/database.yml
        gsub  Gemfile
    

    The change command copies a template config/database.yml with the target database adapter into your app, and replaces your database gem with the target database gem.

    Gannon McGibbon

  • Add rails test:channels.

    bogdanvlviv

  • Use original bundler environment variables during the process of generating a new rails project.

    Marco Costa

  • Send Active Storage analysis and purge jobs to dedicated queues by default.

    Analysis jobs now use the :active_storage_analysis queue, and purge jobs now use the :active_storage_purge queue. This matches Action Mailbox, which sends its jobs to dedicated queues by default.

    George Claghorn

  • Add rails test:mailboxes.

    George Claghorn

  • Introduce guard against DNS rebinding attacks.

    The ActionDispatch::HostAuthorization is a new middleware that prevents against DNS rebinding and other Host header attacks. It is included in the development environment by default with the following configuration:

    Rails.application.config.hosts = [
      IPAddr.new("0.0.0.0/0"), # All IPv4 addresses.
      IPAddr.new("::/0"),      # All IPv6 addresses.
      "localhost"              # The localhost reserved domain.
    ]
    

    In other environments Rails.application.config.hosts is empty and no Host header checks will be done. If you want to guard against header attacks on production, you have to manually permit the allowed hosts with:

    Rails.application.config.hosts << "product.com"
    

    The host of a request is checked against the hosts entries with the case operator (#===), which lets hosts support entries of type Regexp, Proc and IPAddr to name a few. Here is an example with a regexp.

    # Allow requests from subdomains like `www.product.com` and
    # `beta1.product.com`.
    Rails.application.config.hosts << /.*\.product\.com/
    

    A special case is supported that allows you to permit all sub-domains:

    # Allow requests from subdomains like `www.product.com` and
    # `beta1.product.com`.
    Rails.application.config.hosts << ".product.com"
    

    Genadi Samokovarov

  • Remove redundant suffixes on generated helpers.

    Gannon McGibbon

  • Remove redundant suffixes on generated integration tests.

    Gannon McGibbon

  • Fix boolean interaction in scaffold system tests.

    Gannon McGibbon

  • Remove redundant suffixes on generated system tests.

    Gannon McGibbon

  • Add an abort_on_failure boolean option to the generator method that shell out (generate, rake, rails_command) to abort the generator if the command fails.

    David Rodríguez

  • Remove app/assets and app/javascript from eager_load_paths and autoload_paths.

    Gannon McGibbon

  • Use Ids instead of memory addresses when displaying references in scaffold views.

    Fixes #29200.

    Rasesh Patel

  • Adds support for multiple databases to rails db:migrate:status. Subtasks are also added to get the status of individual databases (eg. rails db:migrate:status:animals).

    Gannon McGibbon

  • Use Webpacker by default to manage app-level JavaScript through the new app/javascript directory. Sprockets is now solely in charge, by default, of compiling CSS and other static assets. Action Cable channel generators will create ES6 stubs rather than use CoffeeScript. Active Storage, Action Cable, Turbolinks, and Rails-UJS are loaded by a new application.js pack. Generators no longer generate JavaScript stubs.

    DHH, Lachlan Sylvester

  • Add database (aliased as db) option to model generator to allow setting the database. This is useful for applications that use multiple databases and put migrations per database in their own directories.

    bin/rails g model Room capacity:integer --database=kingston
          invoke  active_record
          create    db/kingston_migrate/20180830151055_create_rooms.rb
    

    Because rails scaffolding uses the model generator, you can also specify a database with the scaffold generator.

    Gannon McGibbon

  • Raise an error when "recyclable cache keys" are being used by a cache store that does not explicitly support it. Custom cache keys that do support this feature can bypass this error by implementing the supports_cache_versioning? method on their class and returning a truthy value.

    Richard Schneeman

  • Support environment specific credentials overrides.

    So any environment will look for config/credentials/#{Rails.env}.yml.enc and fall back to config/credentials.yml.enc.

    The encryption key can be in ENV["RAILS_MASTER_KEY"] or config/credentials/production.key.

    Environment credentials overrides can be edited with rails credentials:edit --environment production. If no override is set up for the passed environment, it will be created.

    Additionally, the default lookup paths can be overwritten with these configs:

    • config.credentials.content_path
    • config.credentials.key_path

    Wojciech Wnętrzak

  • Make ActiveSupport::Cache::NullStore the default cache store in the test environment.

    Michael C. Nelson

  • Emit warning for unknown inflection rule when generating model.

    Yoshiyuki Kinjo

  • Add database (aliased as db) option to migration generator.

    If you're using multiple databases and have a folder for each database for migrations (ex db/migrate and db/new_db_migrate) you can now pass the --database option to the generator to make sure the the migration is inserted into the correct folder.

    rails g migration CreateHouses --database=kingston
      invoke  active_record
      create    db/kingston_migrate/20180830151055_create_houses.rb
    

    Eileen M. Uchitelle

  • Deprecate rake routes in favor of rails routes.

    Yuji Yaginuma

  • Deprecate rake initializers in favor of rails initializers.

    Annie-Claude Côté

  • Deprecate rake dev:cache in favor of rails dev:cache.

    Annie-Claude Côté

  • Deprecate rails notes subcommands in favor of passing an annotations argument to rails notes.

    The following subcommands are replaced by passing --annotations or -a to rails notes:

    • rails notes:custom ANNOTATION=custom is deprecated in favor of using rails notes -a custom.
    • rails notes:optimize is deprecated in favor of using rails notes -a OPTIMIZE.
    • rails notes:todo is deprecated in favor of usingrails notes -a TODO.
    • rails notes:fixme is deprecated in favor of using rails notes -a FIXME.

    Annie-Claude Côté

  • Deprecate SOURCE_ANNOTATION_DIRECTORIES environment variable used by rails notes through Rails::SourceAnnotationExtractor::Annotation in favor of using config.annotations.register_directories.

    Annie-Claude Côté

  • Deprecate rake notes in favor of rails notes.

    Annie-Claude Côté

  • Don't generate unused files in app:update task.

    Skip the assets' initializer when sprockets isn't loaded.

    Skip config/spring.rb when spring isn't loaded.

    Skip yarn's contents when yarn integration isn't used.

    Tsukuru Tanimichi

  • Make the master.key file read-only for the owner upon generation on POSIX-compliant systems.

    Previously:

    $ ls -l config/master.key
    -rw-r--r--   1 owner  group      32 Jan 1 00:00 master.key
    

    Now:

    $ ls -l config/master.key
    -rw-------   1 owner  group      32 Jan 1 00:00 master.key
    

    Fixes #32604.

    Jose Luis Duran

  • Deprecate support for using the HOST environment variable to specify the server IP.

    The BINDING environment variable should be used instead.

    Fixes #29516.

    Yuji Yaginuma

  • Deprecate passing Rack server name as a regular argument to rails server.

    Previously:

    $ bin/rails server thin
    

    There wasn't an explicit option for the Rack server to use, now we have the --using option with the -u short switch.

    Now:

    $ bin/rails server -u thin
    

    This change also improves the error message if a missing or mistyped rack server is given.

    Genadi Samokovarov

  • Add "rails routes --expanded" option to output routes in expanded mode like "psql --expanded". Result looks like:

    $ rails routes --expanded
    --[ Route 1 ]------------------------------------------------------------
    Prefix            | high_scores
    Verb              | GET
    URI               | /high_scores(.:format)
    Controller#Action | high_scores#index
    --[ Route 2 ]------------------------------------------------------------
    Prefix            | new_high_score
    Verb              | GET
    URI               | /high_scores/new(.:format)
    Controller#Action | high_scores#new
